Concrete insert



Patented Oct. 11, 1938 UNITED STATES PATENT OFFICE 1 Claim.

The object of this invention is to devise a novel construction andarrangement of a concrete insert which can be economically manufacturedfrom wrought metal and which can be bonded in the concrete.

A further object of the invention is to devise a novel spacing memberwhich extends beyond and overlaps the ends of the body portion.

With the above and other objects in view as will hereinafter clearlyappear, my invention cc-mprehends a novel construction and arrangementof a concrete insert.

Other novel features of construction and advantage will hereinafter moreclearly appear in the detailed description and the appended claim.

For the purpose of illustrating the invention, I have shown in theaccompanying drawing a preferred embodiment of it, which, in practice,will give satisfactory and reliable results. It is, however, tobe'understood that this embodiment is typical only and the variousinstrumentalities of which my invention consists can be variouslyarranged and organized, and the invention is not limited to the exactarrangement and organization of these instrumentalities as herein setforth.

Figure 1 is a perspective View of a concrete insert embodying myinvention.

Figure 2 is a transverse section, showing the insert as bonded in theconcrete and supporting a hanger.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a bottom plan view of a portion of the insert.

Similar numerals of reference indicate corresponding parts.

Referring to the drawing:

l designates the body portion of the insert which is of conventionalconstruction of wrought metal having a bottom wall 2 with an oblongopening 3, side walls 4, the upper portions of which are bent inwardlyas at 5 and terminate in outwardly extending flanges 6. The portions 5preferably have elongated openings 1 to provide a better bonding of thebody portion with the concrete.

8 designates a spacing member formed of a strip of wrought metal whichis deflected into a general U shape having a top Wall 9, end walls l0and base flanges H. The opposite sides of the top wall 9 are cut awaythroughout their length as at l2 to' receive the side walls 4 of thebody portion. The end walls H] of the insert overhang the ends of theside walls of the body portion, and are preferably flush with the outerfaces of such side Walls. The base flanges II are exterior of the bodyportion and are welded at I2 to the bottom wall 2 of the body portion.The base flanges II are wider than the side Walls of the body portionand are provided with nail receiv ing apertures 13.

The opening 3 in the bottom wall of the body portion provides for theinsertion of a nut or other hanger support I4 which is enclosed withinthe compartment I5.

By this construction a minimum amount of material is employed, therebydecreasing the cost of manufacture without decreasing the efficiency ofthe insert and at the same time providing a slot which will give thesame degree of adjustment.

By notching the top wall of the spacing mem her and extending the endwall beyond the body portion, the insert is reinforced and strengthened.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:-

An insert for concrete, comprising a wrought metal body having sidewalls, open ends and a bottom having an opening therein for insertion ofa hanger support, and a wrought metal insert having the form of aninverted U with a top wall contacting the side walls of the bodyportion, with the end walls of greater width than the top Wall andoverlapping the end edges of the walls of the body portion, and withbase flanges exterior of the body portion having their inner edgespermanently connected with the ends of the bottom of the body portion toform a rigid boxlike construction.
